My current group of PCs adopted the name "the Blinkstone Companions" after they found a malfunctioning Eladrin Lightstone that constantly flickered. They carried the blinkstone around as something of a trophy, and then discovered that it reacted poorly when around heavy doses of magic.
A while back, it was used as an explosive to trigger a magical trap. Goodbye, blinkstone... the party name has sort of faded away, as well.
